> As a followup from code review in [https://github.com/apache/spark/pull/31736#discussion_r588134104] , for `JoinCodegenSupport.genBuildSideVars`, we only need to generate build side variables with default values for LEFT OUTER and RIGHT OUTER join, but not for other join types (i.e. LEFT SEMI and LEFT ANTI). Create this Jira to followup clean up the code.
